Email liu handle i. a 3W0 sh the stiffness and rigidity of the structures and strengthens the part at the point where the bucket is to be attached. C is a dipper or bucket pivoted at the lower end of the member C free to rotate with respect thereto. The dipper is so arranged that when empty its center of gravity comes behind the pivot point, when loaded its center ofgravity comes in front. It is provided with the usual. type of forwardly extending cut ting teeth C and is adapted to be locked against rotational movement when in the ex- "shaft carrying these gears, however, is

mounted in a bracket l) extending downwardly from the boom D and the rear end of the dipper handle is held in such position that the gears are held in mesh with the rack by a roller 1) also on the bracket D. Arms D extending upwardly from the forward end of the dipper handle carry rollers l) which ride along the boom 1) and the bucket is attached to the for 'ard end of the bucket handle in the same way being pivoted in exactly the same manner as is the bucket in the preferred form, the only difference being that in this case, the dipper or bucket handle is immediately behind the bucket and located below the boom instead of being along side of the boom and above the bucket as in the preferred form.

It will be evident that while we have shown in our drawings an operative device, still many changes might be made in size, shape and arrangement of parts without departing nmterially from the spirit of our invention, and we wish therefore that our drawings be regarded as in a sense diagrammatie.

The use and operation of our invention are as follows:

The excavating machine is manipulated for moving it about from place to place, and for rotating the turn-table about its pivot in the usual manner common to all excavating machines of the revolving type. The boom, however, is pivoted on the platform and is adapted to rotate about a horizontal axis. Means are provided whereby the hoisting mechanism on the platform operates to raise and lower the boom.

The dipper handle, it will be noted. is held parallel with the boom, but is free to Fig. l. The operator will then operate the thrusting motor and force the bucket forward into the work until the bucket is full. \Vhen the bucket is full the thrusting motor will. be stopped and the. boom will then be rotated about its axis to lift the bucket away from the work. As soon as the bucket is lifted, the turn-table will be operated to swing the bucket into the dumping position, when the latch will be released, the bucket will tip to dump its contents and as soon as the contents are dumped the force of gravity will close the bucket, the operator being then ready to return the bucket to its position, taking first precaution, of course, to withdraw the bucket by moving the thrusting motor in the opposite direction so that the work can be repeated.

The two forms are exactly the same as far as the operation is concerned except that for some purposes it may be desirable to have the bucket handle located beneath the boom, though in either event the operation is exactly the same and the general arrangement of the parts is, of course, as evident.

We claim;

1. An excavating machine comprising a boom having guide members upon its opposed sides and means for rotating it about a horizontal axis, a motor on the boom, a shipper shaft driven by the motor, a dipper handle, pinion on the shipper shaft, a rack on the handle in mesh with the pinion and a stirrup mounted on the shipper shaft in slidable engagement with the handle, guide members on the forward end of the handle riding in the guide members on the boom and a dipper pivoted on the handle.

2. An excavating machine comprising a boom having on either side flanged members, means for rotating it about a horizontal axis, a motor mounted upon it, a dipper handle having members on its forward end adapted to engage the flanges, a rack on the handle, a shipper shaft on the boom having a pinion in mesh with the rack, a driving connection between the shaft and the motor and a stirrup pivoted on the shaft and in slidable engagement with the handle, a framework downwardly depending from the handle and a bucket pivoted thereupon.

3. An excavating machine comprising a boom made up of channel members, means for rotating it about a horizontal axis. a motor mounted thereupon, a dipper handle adapted at its forward end to engage the aw A26 channel members, a rack on the handle, a shipper shaft on the boom having a pinion in mesh with the rack, a driving connection bet een the shaft and the motor and a stirrup pivoted on the shaft and in slidable engagement with the handle, a frame-Work downwardly depending from the handle and a bucket pivoted thereunon.
